Answer 1

You must pass the 'name' paramter to the Parameters property. http://msdn.microsoft.com/en-us/library/system.activities.statements.invokemethod.parameters(v=vs.110).aspx There is a code example but you are doing your stuff through the WF designer (which is easier than code). Look at the properties for the activity for the Parameters property.

Answer 2

You have to declare that "update1" in the "Arguments" field present in the Workflow designer right below the workflow to pass that arguments to you Invoke Process. Once you declare that argument in the "Argument" field it won't show any error and you can use it to pass that argument to the invoke process. For reference You can use this link....

For passing arguments in Windows Workflow using designer
